The invention provides a guide rail for an automobile seat. The guide rail for the automobile seat at least comprises a slide device and a guide rail body, wherein the slide device is slidably connected with the guide rail body; and preferably, a rolling wheel is arranged at a part which makes contact with the guide rail body, of the slide device. A slide bypass groove accommodating the slide device to pass through is formed in the slide device. In order to prevent influence on slide due to a too large gap between the slide device and the guide rail body, a support block is fixedly connected to the slide device, an arc sheet which is bulged outwards and capable of being deformed after being pressed is arranged on a side surface facing the inner wall of the guide rail body, of the support block, the arc sheet makes contact with and extrudes the inner wall of the guide rail body to provide an effect of support location for the slide device, so that the slide device is prevented from swinging in the left-right direction and up-down direction while moving; and meanwhile, the slide device is prevented from being blocked due to improper stress, so that the slide stability of the guide rail for the automobile seat is improved.
本发明提供一种汽车座椅导轨,至少包括滑动装置和导轨,滑动装置与导轨滑动连接,优选的滑动装置与导轨接触的部分设有滚轮。导轨上设有容纳滑动装置通过的滑动避让槽。为了防止滑动装置与导轨之间的间隙过大影响滑动,滑动装置固定连接有支撑块,支撑块朝向导轨内壁的侧面上设有向外凸出且受压力后能产生形变的弧片,弧片接触并挤压导轨的内壁,以此对滑动装置提供支撑定位的效果,避免滑动装置在移动时在左右上下方向上产生晃动,同时防止滑动装置由于受力不当发生卡顿,提升了汽车座椅导轨的滑动平稳性。
